Ventilating device

Abstract

PURPOSE:To maintain a circumstance in an underground room comfortable by a method wherein moisture in atmosphere is dewed by utilizing subterranean heat effectively by a simple device in which an air supplying pipe is buried into the ground in order to prevent dewing due to ventilation in the underground room. CONSTITUTION:The air supplying pipe 1, whose one opening is communicated with atmosphere and the other opening is communicated with the underground room 2, whose most part is buried into the ground and whose lowest part is provided with a water discharging port 5, and air discharging pipe 7, whose one opening is communicated with the underground room 2 and the other opening is communicating with atmosphere, are provided while a fan 10 is arranged in a ventilating path from the pipe 1 to the atmosphere through the underground room 2 and the pipe 7. The moisture in the atmosphere is dewed by utilizing the subterranean heat effectively through the simple device in which the pipe 1 is being buried into the ground in order to prevent dewing due to the ventilation in the underground room and whereby the circumstance in the underground room may be maintained comfortable without increasing the load of room heating or cooling.
